Effect of temperature and reactant concentration on calcium phosphate precipitation

•Temperature and reactant concentration interacted to define the precipitated phase.•DCPD/OCP mixtures (22 °C) and HAP (45 °C) were obtained under low concentration.•DCPD (22 °C) and DCPD/OCP (45 °C) precipitated under medium and high concentrations.•Particle hydrodynamic radius was not strongly affected by the tested variables.•Surface area results reflected differences in particle morphology among phases.
